Question

When measured at 27°C, the volume of Oxygen gas was 400ml, what would be the new volume at 127°C at constant pressure. please answer the question If you answer the question most helpful for me​

Answer 1

Answer:

300ml

Explanation:

Use relation V1×T1 = V2×T2

Answer 2

Explanation :-

Given :

Initial temperature (T₁) = 27° C

Final temperature (T₂) = 127°C

Initial volume (V₁) = 400 ml

To find :

Final volume (V₂)

Solution :

Converting °C to K : [0°C = 273 K]  

⇒ 27°C = 27 + 273  

⇒ 300 K [Initial volume]

⇒ 127°C = 127 + 273

⇒ 400 K [Final volume]

Using Charles Law : [V₁/T₁ = V₂/T₂]

⇒ 400/300 = V₂/400

⇒ V₂ = (400 × 4)/3

⇒ V₂ = 1600/3

⇒ V₂ = 533.33 ml

∴ Final volume is 533.3 ml.
